Description

Technical field:

[0001] The utility model relates to a detector of a smoke detector of a building fire protection facility. Background technology:

[0002] In traditional fire detection, when encountering the detection of smoke detectors installed at a certain distance above the ceiling grid of a building, it is difficult to accurately locate the smoke detection due to dark light or special location. At this time, it is necessary to conduct a large smoke coverage test at the approximate location of the area where the smoke detector is located. Summary of the invention:

[0003] The utility model provides a detector of a smoke detector for building fire protection facilities, characterized in that: the side walls of an outer shell 3 of an open smoke cake container 1 are connected and fixed by two or more metal supports 4, a first through hole 6 is provided at the center of a bottom surface 5 of the outer shell 3, a first metal tube 7 is connected to the center of the bottom surface 5, the first metal tube 7 is communicated with the first through hole 6, the lower end of the first metal tube 7 is connected to a hollow first telescopic tube 8, the lower end of the first telescopic tube 8 is connected to an adjustable speed blasting device 9, the upwardly open end of the outer shell 3 can be inserted from top to bottom by a downwardly open metal cover 10, a second through hole 11 is provided at the center of the top surface of the metal cover 10, a second metal tube 12 is connected to the center of the metal cover 10, the second metal tube 12 is communicated with the second through hole 11, the upper end of the second metal tube 12 is connected to a hollow second telescopic tube 13, and the upper end of the second telescopic tube 13 is provided with an elbow nozzle 15.

[0004] A certain distance exists between the side walls of the housing 3 and the smoke accumulator 1 to facilitate upward airflow through the first through-hole 6. The smoke accumulator 1 is secured to the housing 3 by welding or screwing two or three metal supports 4, which do not obstruct the flow of smoke. A smoke accumulator 14, which produces a large amount of smoke upon combustion, is placed on the smoke accumulator 1. The smoke generated by the smoke accumulator 14 rises, passing through the metal cover 10, the second through-hole 11, and the second telescopic tube 13, ultimately being ejected from the elbow nozzle 15. When the adjustable-speed blower 9 is activated, the pressurized air generated by the blower 9 passes through the first telescopic tube 8, the first metal tube 7, and the first through-hole 6 into the housing 3, pressurizing the combustion smoke from the smoke accumulator 14 in the smoke accumulator 1 and delivering it to the elbow nozzle 15. The smoke accumulator 15 can be directed to perform coverage testing on smoke detectors in specific locations. The smoke cake holder 1 can hold three or more cigarette cakes to maintain a high smoke output and a certain duration of smoke emission. Due to the obstruction of the ceiling grid, the smoke cake holder 1 cannot normally extend above the ceiling grid. The second telescopic tube 13 solves this problem. The second telescopic tube 13 can pass through the ceiling grid and emit smoke close to the smoke detector being tested.

[0005] The utility model provides a detector for smoke detectors of building fire protection facilities. Since the detector has the characteristics of being able to hold a large amount of smoke and emit smoke, and is convenient for detecting smoke detectors installed in special positions above the ceiling grid, it can solve the problem of smoke detector detection in special environments that is difficult to solve with conventional smoke detector detection tools.

[0008] Example 1:

[0009] See Figure 1 、 Figure 2 The side wall 2 of the upwardly open cigarette holder 1 and the side wall of the shell 3 of the upwardly open cigarette holder 1 are welded and fixed by two metal supports 4. There is a first through hole 6 in the center of the bottom surface 5 of the shell 3 of the cigarette holder 1. A first metal tube 7 is welded to the center of the bottom surface 5. The first metal tube 7 is connected to the first through hole 6. The lower end of the first metal tube 7 is connected to the hollow first telescopic tube 8. The lower end of the first telescopic tube 8 is connected to the adjustable speed blowing device 9. The upwardly open end of the shell 3 is inserted from top to bottom by a downwardly open metal cover 10. There is a second through hole 11 in the center of the top surface of the metal cover 10. A second metal tube 12 is welded to the center of the metal cover 10. The second metal tube 12 is connected to the second through hole 11. The upper end of the second metal tube 12 is connected to the hollow second telescopic tube 13. The upper end of the second telescopic tube 13 has an elbow nozzle 15.

[0010] When the smoke cake 14 is ignited, the adjustable speed blowing device 9 is started, and the pressurized air passes from bottom to top through the first telescopic tube 8, the first metal tube 7, the first through hole 6, and reaches the inside of the shell 3 of the smoke cake container 1, and together with the smoke, the smoke is sent out from the second through hole 11, the second metal tube 12, the second telescopic tube 13, and the elbow nozzle 15 to the area where the smoke detector to be detected is located.

[0011] The cigarette holder 1, housing 3, metal support 4, first metal tube 7, metal cover 10, and second metal tube 12 are made of stainless steel. The first and second telescopic tubes 8 and 13 are made of aluminum alloy, and the elbow nozzle 15 is made of silicone rubber. The adjustable-speed blower 9 uses a 12VDC power supply (commercially available).
